Though there are many indie masterpieces you’ve probably never seen, there are also a fair few that blow expectations out of the water and become smash hits.

When it comes to considering what is and what isn’t an independent movie, there are some fine lines. Technically, Quentin Tarantino’s recent movies such as Inglourious Basterds and Django Unchained could be considered indies as they were produced by The Weinstein Company, which works outside of the Hollywood studio system. But as they have budgets of $50+ million and are full of A-list actors, they aren’t considered "indies" in the typical spirit of the term. All box office tallies in this list are courtesy of Box Office Mojo.

Fahrenheit 9/11 is the highest grossing documentary of all time and it was all made off the back of Michael Moore, and any production costs came from his own pocket.

The Blair Witch Project

The Blair Witch Project changed the way horror movies were made and it was the first horror movie to instigate what Blumhouse Productions has made their business model. Though Blair Witch is only the seventh highest grossing indie movie of all time, as it made $258 million worldwide, it may be much higher if net profit is only taken in to consideration, as the miniscule budget is estimated to be between $200,000 and $500,000.

Though The Full Monty is one of the highest grossing indie movies of all time, it rarely gets talked about as much as the others.

Off a budget of just $3.5 million, the British movie racked up a massive $258 million worldwide.

Though it is written by a Greek screenwriter, it is a largely American production, with the bulk of its budget coming from HBO Films as well as producer Tom Hanks.

Though The King’s Speech features an array of seasoned and award winning actors, such as Colin Firth, Guy Pearce, Geoffrey Rush, and more, and it has spectacular costume and set design, it’d be easy to believe that the movie is a high budget studio movie.
